Hi,
I’m getting an error message: “Certificate authority is not trusted.” while using webview browsers.
On “standalone” browsers like Mull or Cromite I don’t have this error.
Specs:
Android 10
Free Browser v2.8
Mulch Webview v126.0.6478.110
AdAway (root) v6.1.1 with installed certificate
Root with Magisk v27.0
Modules: Systemless Hosts
Magisk Trust User Certs
Open Webview
Private DNS: unfiltered.adguard-dns.com
Anybody knows how to fix this?
Seems like I’ve found the culprit: https://github.com/Magisk-Modules-Alt-Repo/trichromelibrary-squoosh
When I deactivate this module and try again, the error message disappears and shows up again when enabled.
What’s the page, and what cert do you receive?
Could be that your phone lacks the necessary certificate authorities. I don’t think I’ve seen this happen on anything newer than Android 7 before, but maybe some root cert expired that I don’t know about.
If you haven’t already, try a reboot. The WebView server may be initialized once, and if you’ve just activated the cert in Magisk then you may need a reboot to activate it.
If not, I’m guessing the app explicitly does something to only use a particular system trust store.
